Description

Technical Field

[0001] The present application relates to the technical field of gas stove accessories, and more specifically to a valve stem for a gas stove with good versatility. Background Art

[0002] A gas stove is a kitchen appliance that uses liquefied petroleum gas, coal gas, natural gas and other gas fuels as a medium for open flame heating. When the gas stove is working, the gas enters the stove from the air inlet pipe, flows into the burner after passing through the switch valve, and is ignited by the ignition device after mixing with the air to form a flame, which is used to heat the cooker placed on the pot support. The valve stem is set in the switch valve, and the two ends are connected to the valve core and the knob respectively.

[0003] The patent document (CN201259016Y) discloses a valve stem for a gas stove. It can be seen from the drawings in its specification that the valve stem for a gas stove includes a valve stem body, one end of the valve stem body is fixedly connected with two limiting protrusions, and an end of an external valve core close to the valve stem body has a groove, and the limiting protrusion extends into the groove and fits with the groove surface of the groove. When the valve stem body rotates circumferentially, since the limiting protrusion is embedded in the groove, the valve core follows the circumferential rotation to control the size of the gas flow; in addition, in order to facilitate the screwing of the valve stem body, the other end of the valve stem body is assembled with a knob. However, since the limiting protrusion is fixedly connected to the valve stem body, when the width of the groove on the external valve core is larger than the width of the limiting protrusion, the limiting protrusion cannot directly contact the groove wall of the groove when the valve stem body is screwed for the first time, and there is an empty stroke; and when the width of the groove on the external valve core is smaller than the width of the limiting protrusion, the limiting protrusion cannot extend into the groove and drive the valve core to rotate, so the versatility is poor.

[0004] Therefore, there is a need to provide a valve stem for a gas stove with an adjustable width of a limiting component and better versatility. Utility Model Content

[0028] Schematic diagram of a universal valve stem for a gas stove.

[0029] refer to Figures 1 to 4 According to any preferred embodiment of the utility model, a valve stem for a gas stove with good versatility includes a rod body 10, two limit members 20 and two extension members 30.

[0030] Specifically, in any embodiment of the present utility model, if Figure 1 and Figure 2 As shown, the two limiting members 20 are located on the side wall of one end of the rod body 10 and face oppositely. Each of the limiting members 20 has a through first threaded hole 2021 at the end facing away from the rod body 10. Each of the first threaded holes 2021 is threadedly connected with an extension component 30, and the extension component 30 is arranged vertically to the rod body 10.

[0031] It should be noted that, by providing the first threaded hole 2021 on the stopper 20, and threading the extension component 30 with the first threaded hole 2021, the overall width of the stopper 20 and the extension component 30 increases or decreases by screwing the extension component 30. It should be added that when the extension component 30 is completely immersed in the first threaded hole 2021, the overall width of the stopper 20 and the extension component 30 is the smallest. Obviously, compared with the fixed width of the stopper 20 in the prior art, the embodiment of the present application has the advantage of adjustable width of the stopper component, which can match the grooves on the valve cores of different specifications and has the advantage of better versatility.

[0032] Furthermore, since the distances between the grooves on the valve cores of different specifications and the central axis of the valve core are also different, in any embodiment of the present utility model, Figure 1 and Figure 2 As shown, one end of the rod body 10 has two second threaded holes 101 arranged opposite to each other, and each of the second threaded holes 101 is threadedly connected with a stopper 20 .

[0033] It should be noted that by screwing the limiter 20, the distance between the limiter 20 and the central axis of the rod body 10 can be adjusted to adapt to grooves on valve cores of different specifications, further improving the versatility of the gas stove valve stem with good versatility.

[0034] Further, in order to facilitate the extension member 30 to abut against the groove on the external valve core when it is completely immersed in the first threaded hole 2021, and to facilitate the screwing of the limit member 20, in any embodiment of the utility model, Figure 2 As shown, each of the stoppers 20 includes a spiral portion 201 and a support portion 202, wherein the spiral portion 201 is connected to the second threaded hole 101, and the first threaded hole 2021 is provided on the support portion 202, and a cross section of the support portion 202 is square. It should be noted that the spiral portion 201 is cylindrical as a whole, and the support portion 202 is square as a whole, and a thread backing groove is provided between the spiral portion 201 and the support portion 202.

[0035] Further, in the first embodiment of the present utility model, as Figure 2 As shown, the extension component 30 is a threaded rod 301 , and both end surfaces of the threaded rod 301 have a first screwing groove 3011 .

[0036] It should be noted that the side surfaces of the screw rod 301, i.e., an optical axis, are all externally threaded, and the first screw groove 3011 includes but is not limited to a slot, a cross slot, or a hexagonal slot. It should also be noted that when the overall width of the stopper 20 needs to be adjusted, the width of the stopper 20 and the extension part 30 as a whole can be adjusted by simply screwing the extension part 30.

[0037] However, since the extension component 30 can only move in a single direction relative to the limit member 20, assuming that the center plane of the groove on the external valve core coincides with the center axis of the external valve core, this will result in that after the end of the rod body 10 having the limit member 20 is engaged with the groove, the center axis of the rod body 10 and the center axis of the external valve core are eccentrically arranged, making it inconvenient to screw.

[0038] In view of this, in the second embodiment of the present utility model, as Figure 3As shown, the extension component 30 is two screw rods 302, and the two screw rods 302 are of equal length. When it is necessary to unify the overall width at the limit member 20, the two screw rods 302 only need to move toward or away from each other, and the moving stroke is equal, so that the central axis of the rod body 10 can coincide with the central axis of the external valve core. To facilitate the screwing of the screw rods 302, the end faces of the two screw rods 302 facing each other have a second screw groove 3021, and the second screw groove 3021 includes but is not limited to a straight groove, a cross groove or a hexagonal groove.

[0039] Furthermore, in order to facilitate the assemblers to screw the two screw rods 302 to the same stroke, in the second embodiment of the utility model, the abutment portion 202 is provided with an angle scale line (not marked in the figure) on the side of the first threaded hole 2021, and the assemblers can remember how many turns and how much angle the screw rods 302 have been rotated according to the angle scale line.

[0040] Further, in any embodiment of the present invention, if Figure 1 and Figure 4 As shown, the end of the rod body 10 away from the limiting member 20 has an insertion portion 102 , and the insertion portion 102 has a plurality of retaining spring grooves 1021 .

[0041] It should be noted that the insertion part 102 is a cylinder, and one side surface of the cylinder is cut by a plane parallel to the central axis direction of the cylinder. The insertion part 102 is inserted into the external screw. In addition, in the utility model, the number of the retaining spring groove 1021 is one, and the retaining spring groove 1021 is located at the root of the insertion part 102.

[0042] In summary, the gas stove valve stem with good versatility based on the embodiment of the present application is explained, which provides the gas stove valve stem with good versatility with advantages such as adjustable width of the limiting component and better versatility.
